To execute a larger number of simultaneous connecting processings while suppressing the rising of a cost and keeping a communication quality by providing a control means, etc., controlling a switch means and an interchanging means so as to connect the output terminal of each generating means to mutually different antennas.
A control means 446 instructs to convert a received signal corresponding to a first-order antenna judged by receiving signals 431 and 432 from RF to IF according to the judging result of a judging part 445 at each receiving time slot. On the other hand the control part 446 based on the judging result controls switch setting obtained by combining a cross switch 460, antenna switching switches 495, 496 and circulators 492 and 493 to sort each of two systems (basing on the base band signal of TDMA processing parts 471 and 472 as a reference) using different carrier waves to optimum antennas among four antennas 401 to 404.
